Hulling and gleaming clover-seed



'UNITE ""ToaZZ/wkom'z't maycoaeem.'

Be it known that f I, MARTIN` I-I. MANS:- "FIELDQof Ashland, @inthe county of Ashland and Statel of Ohio, have` invented fa ew and.` useful Improvement in Clover `:I-Iulling and Cleaning Machines;` andA I do )hereby declare that `the following isla full i and exact description thereof, referencebeing `had to thejaccompanying."drawings, `making a part of this specification, Figure `l, being" a `longitudinal vertical section through the centeroffmy improved clover lhulling and cleaning machine; Figs. 2 and side elevations of "lthe machine; Fig. 4, a` vertical transverse section in the `line www i of Fig. 3, and Fig. 5a view of a portion of f `the machine detachedl `Similarletters indicate like parts in all l the `1igures. y

` The nature of my invention consists in the employment offa -considerably greater e `length of screenthanfhas heretofore been fused infyclover hulling f and cleaning machinesf and in "receiving :the `.seeds which fa-llfrom saidgsereen `upon an endless apro-n which conveys the. seeds to a receptacle 7c, placedimmediatel, in front of and near to the winnowing an d. e l Y Thecloverhullingjcylinder a, and con- .Cave b, may `belconstructed in any well- `lrnown or usualmanner. The seeds and haif as they are discharged `from the said concave,` are thrown upon the screen e. The `screen. e,n1`ayl` be `suspended and vibrated in "any well lrnown orusual manner. I generally supportthe end `of the sc-reen which is nearest `to `the hulling concave, upon a rankshaft l, and suspend its opposite end ofstirrups: The said crankshaft impartv to the` said screen af `compoundfvertical and longitudinal vibratory movement.

Inclined boards s, s, are secured to the v j `sides of the Amachine, which serve to concentrate the seeds as they fall from the `lscreen e, andconduct them to the endless `apron f.. e i Ihe long screen e, enables the seeds to be l y thoroughly"` sifted from the chaff; the said` screen is so long, thatlablast of great power will not act withsuficient `force at the rear end "ofthe machine to carry off any i. fan the seeds willibe blown, some distance MARTIN H.

ofthe apron f, which will bring them back and discharge them into the trough 7c. Should dust fall upon the apron with the seeds, it will be blown off as it approaches the fan, or at the moment that the apron begins to turn `upon its moving cylinder g. Thus it will `beseenthat the combined (use of a long screen, with an endless apron un- "ment of the said long screen, endless apron, :and strong blast, is to perfectly clean the seeds at a single operation, which has never been done by any other machine. y

, A screen z', works in the seed trough la, and conducts the seeds into the bottom of the elevator boX n, where they are acted upon and elevated by the elevators upon. `the band p, which discharges them at `the `spoutg, where a bag may be placed to receive them.

The various parts of the machine are connected to each other as follows-fviz: Av

`of the fan CZ, is banded to the pulley Iw,

on the shaft of the hulling cylinder. The elevator band 79 passes aroundthe pulley y, on the outer `end of the screwvz' and receives motion therefrom.

What I claim as my invention and desire to secure by Letters Patent, is-

The arrangement and `combined operation of the screen e, the endless conveyor f, and the fan al, in such a manner as to enable a strong blast to be employed without wasting the seeds, substantially as herein set forth.

The above specification of my new and luseful improvement in clover seed hulling andcleaning machines signed this 28th day of Deer. 1854.
